Question About Brass

[rebapuck]

I want to make a mold for polymer clay out of thin brass discs and washers. What can I use to hold the brass pieces together in a 265* oven for 5 minutes?

I believe 95/5 solder would work.

Thanks. But I don't have solder or a torch. I think I'm going to try JB Weld. It has a high temp of 550*.
